4 Getting Started with CES EduPack
The following exercises give an overview of CES EduPack and will teach you how to use the core
functionality. The exercises in Chapter 5 go into further detail and explore some of the software’s more
specialized features. There is also comprehensive help file within the software that gives more detailed
guidance, as well as case studies with loadable project files.
4.1 Brief Description of CES EduPack
The main tools in CES EduPack are:
• BROWSE
Explore the database and retrieve records via a hierarchical index or tree.
• SEARCH
Find information via a full-text search of records.
• SELECT
The central hub of CES EduPack, used to apply the Rational Material Selection
methodology. A powerful selection engine that identifies records that meet an
array of design criteria and enables trade-offs between competing objectives.
• CHART
Create charts and add formatting and labels to illustrate your point.
The following exercises cover the use and functionality of these tools.

4.2 Browsing and Searching
Exercise 1 Opening the Database
If you have more than one database installed, CES EduPack will show the Databases dialog. The
following exercises use the MaterialUniverse and ProcessUniverse tables, which are part of every
Granta database.
The Edition Homepage will open, showing a list of the available tables and a graphic for each subset.
Click on a subset name to show its description. Use the information icon next to the database name to
show a detailed description.
• Swap between the available subsets and see how they have different applications and data
Click on a subset in the Edition Homepage to select it. The information displayed is for the currentlyselected subset. Notice that the Browse tree in the left pane updates to the currently selected subset.
• Change to the PROCESSUNIVERSE table
Click on ProcessUniverse and notice that the Browse tree in the left pane updates to show the new
table.
• CLOSE the HOMEPAGE
Click on the cross at the top of the Homepage tab. This page can be reopened at any time from View
menu - Home.

• Change to the MATERIALUNIVERSE table
With the Homepage closed, navigate to different tables using the Table drop-down in the Browse
pane.

Select the Table MaterialUniverse and the Subset All materials.
• Find a record for STAINLESS STEEL
• Find a record for CONCRETE
• Open the GENERIC record for POLYPROPYLENE
Generic records are records at the folder level and give general information on the material, rather than
data on a specific variant. Generic records have their own icon
. Double-click to open.
• Open a POLYPROPYLENE record
Double-click on the record name in the tree
Click on hyperlinked attribute names. In Level 1 and Level 2 databases, this will bring up a Science
Note, giving details of the underlying science and calculations for the attribute. In Level 3 databases,
this will bring up the design note, which provides background information on properties, test notes, and
selection guidelines. From a design note, there will also be a link to the corresponding Science Note.
Right-click on the datasheet to see a context menu with further actions e.g., locate in Browse tree, copy
the datasheet, print the datasheet, export the data to an FE package format.

Use the limit bars for guidance on suitable values. Enter the limits – minimum or maximum as
appropriate – and click Apply. If a reference record is set, its values for each property will be shown to
the right of the min/max entry boxes.
Example results: Aluminum nitride, Alumina, Silicon nitride.
Some properties have discrete values, rather than numeric ranges.
• Edit this limit stage and search for materials with non-opaque TRANSPARENCY.
Under Optical Properties, refine by transparency using the drop-down and tick Translucent,
Transparent, and Optical quality. Click Apply.
Example results: Alumina (translucent) and Diamond.

Exercise 6 Selection Using a Graph Stage
When plotted on a Graph Stage, records can also be filtered using the charting Box and
Line Selection tools. This provides a more qualitative approach to filtering.
• Make a BAR CHART of YIELD STRENGTH (σy)
Set the y-axis to Yield strength (elastic limit).

• Use a BOX SELECTION to find materials with high values of YIELD STRENGTH
Click Box Selection
, then click-drag-release to define the box.
• Add DENSITY (ρ) to the other axis
Either: highlight Stage 1 in Selection Stages, right-click and choose Edit Stage from the menu; or
double-click the axis to edit.
• Use a BOX SELECTION to find materials with high STRENGTH and low DENSITY
• Use a LINE SELECTION to find materials with high values of the specific strength σy / ρ
Click Gradient-Line Selection
, then enter slope in the dialog, in this case 1. Click on the graph to
position the line through a particular point. Click above or below the line to select an area, in this case
above the line for high values of σy / ρ. Drag the line upwards to refine the selection to fewer materials.

Example results: CFRP, Titanium alloys, Magnesium alloys.
• DELETE ALL STAGES
Using a Tree Stage, records can be filtered based on their links to records in other
data tables, or based on the database hierarchy (tree).
